Best Video Codec for compressing Anaglyph 3D Footage?

Hello All,

We need to deliver a couple of Anaglyph 3D videos (for use with Red-Cyan cardboard 3D glasses) to a client for approval.

Here's the problem: When we compress the Anaglyph 3D footage to MPEG-2 DVD for example, for easy viewing, the compression creates all sorts of unwanted, and seriously bad-looking "ghosting" artifacts in the footage.

We are going to try Quicktime compression next, possibly H264.

Does anyone know a Codec that:

a) Compresses Anaglyph 3D footage without creating weird "visual artifacts" in the process?

b) Can be played back easily by clients with no tech experience? (e.g. requires only Windows Media Player, or Quicktime Player to play back)


Lagarith Codec works fine for this. But the files are pretty big, and we'd have to walk our clients through installing the Lagarith Codec on their PCs... Also, Lagarith doesn't work on Macs currently.

So once more: What common PC or Mac video codec can compress 3D Anaglyph footage without chewing it up completely?

It can't be anything too exotic, otherwise we have to talk out clients through installing custom video codecs on their machines...

Thanks for any help,

DePaint

Theres no codec specialised in Anaglyph 3D encoding that i know of. Theres not much tricks that can be used because the 3D information is 'baked' in the chroma channels.

You'll just have to use a higher bitrate, probably quite a lot higher.

I'd recommend you to use the (free) x264 codec for anything that supports H.264 playback.
Its open source and regarded as the best H.264 codec around.

DPC uses Jpeg2000 compression. Not sure if it is used for anaglyph movies though.

OK, I'll try that.

One Q though: Is the x264 codec output compatible with ordinary Quicktime Player on PC/Mac?

if you mean if you can select it as encoder in quicktime exporter, sorry no.
I'd stay away from quicktime as exporter though. It can give some troubles on non-mac machines.

Also, quicktime's H.264 encoder is quite known to be a not so good encoder in terms of quality.


What format is your source video in? Maybe i can suggest you something else (that works with x264).

Source video is .AVIs compressed with the Lagarith "Lossless" Codec. (Excellent visual quality, but pretty large filesizes)

The client we are delivering to may have Macs or PCs to play the footage back on.

We don't know for sure.

We are thinking of delivering everything as QT .MOVs on a DVD-R, for playback on Quicktime Player, for PC or Mac.

Will x264 compression work with any Quicktime player?

Theres is a special version of x264 that can be used for avi files.

So if quicktime can read/write avi files then it should be selectable (in windows at least, dont know about mac).
Last time i checked quicktime needed a plugin to play avi files? Unless that has changed in more recent versions?

Problem solved!

We bought Imtoo Video Converter, which does a great job converting .AVIs to Quicktime .MOVs.

http://www.imtoo.com/video-converter.html

You can simply specify a filesize (e.g. 500 MBs for a 2 minute clip) and the Quicktime output comes out looking just great. (quite sharp & detailed... almost as good as the original)

So far we have no problems encoding Red-Cyan Anaglyph 3D videos with it. We've encoded 9 Anaglyph 3D videos to Quicktime with it. The Anaglyph 3D effect and overall sharpness of the video survives the transcoding from AVI to Quicktime pretty well so far.

I highly recommend the Imtoo software to anyone who has similar problems. Its only 60 bucks to buy...

I do this, is with avisynth, which is free, an .avs script and x264.
I suspected that Imtoo Video Converter maybe uses avisynth. and yes, it does.

I use avisynth to have control over the different color profiles used by players: bt.601 bt.709, some players do whatever they want with color...
